According to the research results of Professor Richard Lynn, the average IQ values ??of different races are slightly different. IQ standards and levels are generally measured according to IQ tests, which mainly examine observation, memory, imagination, creativity, analytical judgment, thinking ability, adaptability, reasoning ability, etc., including literary quotient (CQ), etc. etc.

On the IQ world map drawn by Professor Linn, Jews have the highest IQ, with an average of over 125, followed by Germany at 109, the Netherlands at 107, and Poland at 106. Europeans and East Asians have the highest average IQ in the world. , the average value is 105.

The following rankings are Eskimos (91), Southeast Asians (87), Native American Indians (87), indigenous peoples of the Pacific Islands (85), South Asians and North Africans (84), Saharans South Desert Africans (67), Australian Aboriginals (62). The areas with the lowest racial IQ are the jungles of the desert plateau of South Africa and the Pygmies of the Congo (Brazzaville) rainforest, with an average IQ of 54.

IQ, that is, intelligence quotient, is an index that compares an individual's intelligence test scores with those of subjects of the same age. It is a standard for measuring the level of an individual's intelligence. The concept of IQ was proposed by Professor Terman, a psychologist at Stanford University in the United States.

Factors affecting IQ:

1. Heredity: Generally speaking, if parents have high IQ, their children will not have low IQ. This genetic factor is also reflected in blood relationships. Children whose parents are both locals have an average IQ of 102; children born to parents who marry in other provinces have an IQ of 109; and if the parents are cousins, there is a significant increase in children with low IQs. ?

2. Breast milk: Breast milk contains a variety of active substances that promote children's intellectual development. In particular, taurine, which has an important impact on intellectual development, is 10 times higher than that of milk. According to surveys, children who grew up on breast milk have IQs about 3 to 10 points higher than those who grew up on milk substitutes.

3. Diet: Children who eat too much meat or are gluttonous will have reduced intelligence. The intelligence of children who skip breakfast will be affected. This is because the protein, sugar, vitamins and trace elements consumed in breakfast are all important ingredients for brain health.

4. Weight: Children who weigh 20% more than normal children will have lower vision, hearing, and ability to receive knowledge. This is because too much fat in obese children enters the brain, which will hinder the development of nerve cells and nerve fiber proliferation.

5. Environment: Children who live in a boring environment, such as abandoned babies, do not receive maternal love and good education, and their IQs will be lower. According to research and surveys, the average IQ of such children is only 60.5 when they are 3 years old. On the contrary, the average IQ of 3-year-old children in a good environment is 91.8.

6. Drugs: Certain drugs can affect children's intelligence. For example, long-term use of anti-epileptic drugs can lower IQ. After stopping the drugs for a few years, IQ will improve.
